Embodiment Construction

[0063]The description below is directed to synthetic aperture ultrasound tomography systems for imaging a medium such as patient tissue, along with ultrasound waveform tomography methods for acquiring and processing data acquired from these systems, or other systems that may or may not be available in the art.

[0064]The synthetic-aperture breast ultrasound tomography system of the present invention uses synthetic-aperture ultrasound to obtain quantitative values of mechanical properties of breast tissues. In this system, each transducer element transmits ultrasound waves sequentially, and when an ultrasound transducer element transmits ultrasound waves propagating through the breast, all ultrasound transducer elements (at least within a portion of an array) simultaneously receive ultrasound reflection / transmission, or forward and backward scattering signals. The ultrasound reflection / transmission signals are used to obtain quantitative values of mechanical properties of tissue featur...
